Dehumidifier VS Air Purifier

Anyone living near the coast or tropics would have experienced the effects of humidity; the feeling of sticky skin and air thick with water vapor will leave everyone feeling uncomfortable within their own home. The excessive moisture in the air will also be detrimental to your home, causing rot and mold growth to set in. Quite self-explanatory, a dehumidifier gets rid of all this excessive moisture, restoring the home to optimum humidity levels.

But what about air born pathogens leading to allergies and other respiratory ailments? Will a dehumidifier do its bit not only to remove excess but moisture, but to clear the air as well? The answer is yes and no.

Air Purifier or Dehumidifier

So you are constantly sneezing, wheezing and coughing inside your own home, and you have established that something in the air is making you sick. But which appliance should you invest in? What is the difference between a dehumidifier and an air purifier?

  • Dehumidifiers

    As mentioned, high humidity levels can lead to respiratory problems and allergies. A dehumidifier’s main function is to suck excessive moisture from the air and restore the room to a normal humidity level. A dehumidifier does nothing to clear or filter the air. However, a dehumidifier does its bit to get rid of mold and dust mites, both significant contributors to allergies and asthma. Mold and dust mites require moisture to survive and flourish. When humidity levels fall below 50%, dust mites and mold will dry out and die.

  • Air Purifiers.

    The name should say it all. An air purifier simply circulates the air through a filter, removing air born pollutants, including smoke particles. However, it does nothing to control the humidity levels inside your house. A purifier can also combat the development of mold by removing spores from the air, but excessive moisture will cause mold to continue coming back. Dust mites can also be easily filtered and removed. However a purifier can get rid of pollutants a dehumidifier cant, like pet dander and pollen, two major culprits in the cause of allergies.
    Certain air purifiers produce ozone as an additional feature to eliminate odor.

Summary

Air purifiers and dehumidifiers serve different functions. Before you choose one or the other, you need to determine your ultimate goal. A dehumidifier will not clear the air, but indirectly contribute to cleaner air by preventing mold and dust mites to develop. Air purifiers will suck pollutants from the air, but will do nothing for humidity levels.

If you have a home both high in humidity and air born allergens (smoke, pet hair, pollen) the best solution is a dehumidifier/air purifier combo. Based on dehumidifier reviews, customers using combo believe it to be the perfect addition to any home suffering from allergies and asthma.
